Rodeostat Software Overview

Software

The software available for the Rodeostat consists of the device firmware which runs on the Teensy 3.2 development board and a Python Library for communicating with the potentiostat from the host PC.

Teensy 3.2 firmware

(in main repository - see the "firmware" sub-directory)

Allows direct/manual control of electrode potential from host PC
Provides serial API for controlling device over USB/Serial using messages in JSON format

Currently implemented methods:

Cyclic voltammetry
Linear sweep voltammetry
Sinusoidal voltammetry
Constant voltage voltammety
Chronoamperometry
Multistep voltammetry

iorodeo-potentiostat

Python library provides a high-level interface for configuring/controlling the potentiostat and for streaming back data to the host PC during measurements. Available on PyPI https://pypi.python.org/pypi/iorodeo-potentiostat.

The Python software library provides methods to:

Set/get the parameters used for the voltammetric tests
Select and run voltammetric tests and collect data from the device (time, voltage, current)
Set/get the ranges for the output voltage and current measurement
Set/get the sample rate used for acquiring data during measurements
Allows direct/manual control of electrode potential and current measurement from host PC

Rodeostat Web App Software

The software provides a user friendly graphical interface running in a web browser and allows the user to configure test parameters, visualize test results and save data. More information can be found here: https://blog.iorodeo.com/rodeostat-software/
